      from time to time by resolution of the Board of Directors;

(b)   The dividend rate per annum of such series,  the quarterly  payment dates
      for  dividends  on  shares  of such  series,  and  the  date  from  which
      dividends  on  shares of such  series  shall be  cumulative  (hereinafter
      called  the "date of  cumulation"),  which  date of  cumulation  shall be
      identical for all shares of such series;

(c)   The price or prices at which,  and the terms and conditions on which, the
      shares of such series may be  redeemed  at the option of the  Corporation
      (hereinafter called the "optional redemption price");

(d)   The  amount or  amounts  payable  upon the  shares of such  series in the
      event  of  voluntary  liquidation,  dissolution  or  winding  up  of  the
      Corporation;

(e)   Whether  or not the  shares  of such  series  shall  be  entitled  to the
      benefit  of a  sinking  fund  or a  purchase  fund to be  applied  to the
      purchase or redemption of shares of such series, and if so entitled,  the
      amount of such  fund and the  manner of its  application,  including  the
      price or prices at which the  shares of such  series may be  redeemed  or
      purchased through the application of such fund;

(f)   Whether or not the shares of such series shall be made convertible  into,
      or  exchangeable  for,  shares of any other  class or  classes  or of any
      other  series  of the  same or any  class  or  classes  of  stock  of the
      Corporation and, if made so convertible or  exchangeable,  the conversion
      price or prices, or the rates of exchange,  and the adjustments  thereof,
      if any, at which such  conversion or exchange may be made,  and any other
      terms and conditions of such conversion or exchange; and

(g)   Whether or not the issue of any additional  shares of such series, or any
      future  series in addition to such series,  or of any shares of any other
      class of stock (except junior stock,  as hereinafter in this Class A Part
      defined) of the Corporation  shall be subject to restrictions and, if so,

III.  Series.

IV.   Out  of the  net  profits  or  net  assets  of  the  Corporation  legally
      available for  dividends  the holders of Class A Preferred  Stock of each
      series shall be entitled to receive,  in  preference  to the Common Stock
      but pari passu with any additional  class of cumulative  preferred  stock
      heretofore  authorized or which may  hereafter be authorized  pursuant to
      the  provisions  of  Paragraph  10 of  Section 2 of  Article  IV of these
      Articles  of  Incorporation,  when  and  as  declared  by  the  Board  of
      Directors,  dividends  at the per annum rate for such series fixed by the
      Board of  Directors  pursuant to the  Paragraph  II of this Class A Part,
      and no  more,  payable  quarterly  on the  dates  fixed  by the  Board of
      Directors  pursuant to said  Paragraph II for such  series,  in each case
      from the date of cumulation of such series;  and such dividends  shall be
      cumulative  (whether or not in any dividend period or periods there shall
      be net profits or net assets of the  Corporation  legally  available  for
      the payment of such  dividends),  so that, if at any time full cumulative
      dividends,  as  hereinafter  in this Class A Part defined,  to the end of
      the then current  dividend period upon the outstanding  Class A Preferred
      Stock of all series  shall not have been paid or  declared  and set apart
      for  payment,  the  amount of the  deficiency  shall be fully  paid,  but
      without  interest,  or  dividends  in such  amount  declared on each such
      series  and set apart for  payment,  before  any sum or sums shall be set
      aside for or applied to the purchase or  redemption  of Class A Preferred
      Stock of any series and before any  dividend  shall be  declared  or paid
      upon or set apart  for,  or any other  distribution  shall be  ordered or
      made in  respect  of,  any  junior  stock and before any shares of junior
      stock  shall be  purchased,  redeemed  or  otherwise  acquired  for value
      (except  in  exchange  for or with  the  proceeds  of the  issue of other
      junior stock) by the Corporation.

                All dividends  declared on the Class A Preferred Stock shall be
      declared pro rata so that the amounts of dividends per share  declared on
      the Class A Preferred  Stock of different  series shall in all cases bear
      to each other the same proportions that the respective  dividend rates of
      such respective series bear to each other.

V.    After full cumulative  dividends to the end of the then current  dividend
      period upon the  outstanding  Class A Preferred Stock of all series shall
      have been paid or declared  and set apart for  payment,  the  Corporation
      shall  set  aside  as a  sinking  fund  or  purchase  fund,  when  and as
      required,  out of any  funds  legally  available  for  that  purpose,  in
      respect  of each  series of Class A  Preferred  Stock any shares of which
      shall at the time be  outstanding  and in respect of which a sinking fund
      or  purchase  fund  for the  purchase  or  redemption  thereof  has  been
      provided for in the  resolution or  resolutions  referred to in Paragraph
      II of this Class A Part,  the sum or sums  required  by the terms of such
      resolution  or  resolutions  as a  sinking  fund or  purchase  fund to be
      applied in the manner specified therein.

VI.   Out  of any  net  profits  or  net  assets  of  the  Corporation  legally
      available for dividends remaining after full cumulative  dividends to the
      end of the then  current  dividend  period upon the  outstanding  Class A
      Preferred  Stock of all series  shall have been paid or declared  and set
      apart for payment and after the  Corporation  shall have complied or made
      provision for compliance  with the provisions of the foregoing  Paragraph



      V of this  Class  A Part  in  respect  of any  and  all  amounts  then or
      theretofore  required  to be set  aside  or  applied  in  respect  of any
      sinking fund or purchase  fund  mentioned  in said  Paragraph V, then and
      not  otherwise,  the holders of any junior  stock  shall,  subject to the
      provisions  hereof and of any  resolution or  resolutions of the Board of
      Directors  with respect to any series of Class A Preferred  Stock adopted
      pursuant  to  Paragraph  II of this Class A Part,  be entitled to receive
      such  dividends  as may from  time to time be  declared  by the  Board of
      Directors.

                In the  event of the  issue  of  additional  Class A  Preferred
      Stock  of any  then  existing  series,  all  dividends  paid  on  Class A
      Preferred  Stock of such  series  prior to the  issue of such  additional
      Class A  Preferred  Stock  and all  dividends  declared  and  payable  to
      holders of record of Class A  Preferred  Stock of such series on any date
      prior to such  additional  issue shall be deemed to have been paid on the
      additional Class A Preferred Stock so issued.

VII.  So long as any shares of the Class A Preferred  Stock of any series shall
      be outstanding,  the right of the Corporation to make any distribution on
      junior  stock,  as  hereinafter  in this Class A Part  defined,  shall be
      subject to the following limitations:

(a)   If and so long as the junior stock equity ratio,  as  hereinafter in this
      Class A Part defined,  is 20% or more but less than 25%, the  Corporation
      shall  not  make,  during  the  twelve  months'  period  ending  with and
      including  the  date  of  any  proposed  distribution  on  junior  stock,
      distributions  on junior stock  (including the proposed  distribution  on
      junior stock)  exceeding in aggregate  amount 75% of the consolidated net
      income of the  Corporation and its  subsidiaries,  as hereinafter in this
      Class A Part  defined,  for the twelve  months'  period  ending  with and
      including  the  second  calendar  month  preceding  the date on which the
      Board of Directors shall  authorize such proposed  distribution on junior
      stock; and

(b)   If and so long as the junior  stock  equity  ratio is less than 20%,  the
      Corporation  shall not make,  during the  twelve  months'  period  ending
      with  and  including  the date of any  proposed  distribution  on  junior
      stock,   distributions   on  junior   stock   (including   the   proposed
      distribution  on junior stock)  exceeding in aggregate  amount 50% of the
      consolidated  net income of the Corporation and its  subsidiaries for the
      twelve  months'  period  ending with and  including  the second  calendar
      month  preceding the date on which the Board of Directors shall authorize
      such proposed distribution on junior stock.

       Certain Voting Rights of Class A Preferred Stock as to Directors
       ----------------------------------------------------------------

VIII. Except as otherwise  required by the statutes of the State of Iowa and as
      otherwise  provided  in this  Class A Part,  the  holders  of the Class A
      Preferred  Stock and the holders of the Common Stock shall vote  together
      as one class on all matters  submitted to a vote of  stockholders  of the
      Corporation,  with each share of Class A  Preferred  Stock and each share
      of  Common  Stock  being  entitled  to  one  vote.   Notwithstanding  the
      foregoing,  if and  whenever  full  cumulative  dividends  for  four  (4)
      quarterly  dividend  periods  upon any series of Class A Preferred  Stock
      shall be unpaid,  the holders of the Class A Preferred Stock and of other



      shares of  preferred  stock  ranking  pari passu  therewith,  voting as a
      class,  shall be  entitled  to elect a  majority  of the total  number of
      directors,  and the holders of Common Stock,  voting as a separate class,
      shall be entitled to elect the  remaining  directors.  Whenever the right
      shall  vest in the  holders of the Class A  Preferred  Stock and of other
      shares of  preferred  stock  ranking  pari passu  therewith to elect such
      directors,  the Board of Directors  shall, at least fifteen days prior to
      such annual  meeting at which such  dividends  remain accrued and unpaid,
      cause to be mailed to each  stockholder,  at his last known  post  office
      address  as shown on the stock  records of the  Corporation,  a notice to
      this  effect.  At all meetings of  stockholders  where the holders of the
      Class A Preferred  Stock and of other  preferred stock ranking pari passu
      therewith shall have such right to elect such directors,  the presence in
      person or by proxy of the holders of a majority of the  aggregate  number
      of  outstanding  shares of Class A  Preferred  Stock shall be required to
      constitute  a  quorum  for  the  election  of  such  directors;   further
      provided,  however,  that the absence of a quorum of the holders of Class
      A Preferred  Stock shall not prevent the  election at any such meeting or
      adjournments  thereof of  directors in the usual manner by the holders of
      Common  Stock if the  necessary  quorum of the holders of Common Stock is
      present  in  person  or by proxy  at such  meeting.  When  all  dividends
      accrued  and unpaid on the Class A  Preferred  Stock shall have been paid
      or  declared  and set apart for  payment,  holders  of Class A  Preferred
      Stock and of other  preferred stock ranking pari passu therewith shall at
      the next annual  meeting be  divested of their  rights in respect of such
      election  of a majority  of the  directors,  and the voting  power of the
      holders  of the  Class A  Preferred  Stock and of other  preferred  stock
      ranking  pari passu  therewith  and the holders of the Common Stock shall
      revert to the status existing  before the first dividend  payment date on
      which  dividends  on the Class A  Preferred  Stock were not paid in full;
      but always  subject  to the same  provisions  for  vesting  such  special
      rights  in the  holders  of the  Class A  Preferred  Stock  and of  other
      preferred  stock ranking pari passu  therewith in the event  dividends on
      the Class A Preferred  Stock shall again become  accrued and unpaid in an
      amount  equal to four  quarterly  dividends.  Vacancies  among  directors
      elected  by  holders of Class A  Preferred  Stock and of other  preferred
      stock ranking pari passu therewith  during any period for which directors
      shall  have  been so  elected  shall be filled  until the next  annual or
      special meeting for the election of directors,  by the vote of a majority
      of the  remaining  directors  elected by the holders of Class A Preferred
      Stock  and  of  other  preferred  stock  ranking  pari  passu  therewith.
      Vacancies among directors  elected by the Common Stock shall be filled by
      the vote of a majority of the remaining  directors elected by the holders
      of Common  Stock  until  the next  annual  meeting  for the  election  of
      directors or special meeting in lieu thereof.

               Certain Voting Rights of Class A Preferred Stock
               ------------------------------------------------

IX.   So long as any shares of the Class A Preferred  Stock of any series shall
      be outstanding,  the Corporation  shall not,  without the consent by vote
      or in writing of the  holders of a majority  of the shares of the Class A
      Preferred  Stock of all series at the time  outstanding,  considered as a
      class without regard to series,

(a)   Sell all or substantially  all its assets or consolidate or merge with or
      into any other  corporation or corporations,  except that no such consent



      or vote shall be  required if such sale,  consolidation  or merger or the
      issuance  or  assumption  of all  securities  to be issued or  assumed in
      connection  with  such  sale,  consolidation  or merger  shall  have been
      approved,  permitted or ordered by the Securities and Exchange Commission
      or by any  successor  commission  or by any  regulatory  authority of the
      United   States  of   America   having   jurisdiction   over  such  sale,
      consolidation  or merger or the issuance or  assumption  of securities in
      connection  therewith;  provided,  however,  that the  provisions of this
      subparagraph   (a)  shall  not  apply  to  (i)  a  consolidation  of  the
      Corporation  with, or a merger into the  Corporation  of, any  subsidiary
      of the  Corporation,  or (ii) the  purchase or other  acquisition  by the
      Corporation  of the  franchises or assets of another  corporation  in any
      manner  which does not involve a  consolidation  or merger under the laws
      of the State of Iowa; the term  "subsidiary" as used in this subparagraph
      (a) shall mean any corporation all of the outstanding  shares of stock of
      which (except  directors'  qualifying  shares) at the time shall be owned
      directly  or  indirectly  by  the   Corporation   or  by  a  wholly-owned
      subsidiary of the Corporation; or

(b)   Increase  the total  authorized  amount of Class A  Preferred  Stock,  or
      authorize any other  preferred  stock on a parity  therewith with respect
      to the  payment  of  dividends  or the  distribution  of assets  upon the
      dissolution,  liquidation  or  winding  up of  the  Corporation,  whether
      voluntary or involuntary; or

(c)   Issue any additional  shares of preferred stock (including the reissuance
      of reacquired  preferred  stock) ranking on a parity with the outstanding
      shares of Class A Preferred  Stock  either as to the payment of dividends
      or as to the  distribution  of assets unless (i) the  consolidated  gross
      income  of  the  Corporation  and  its  subsidiaries   (after  all  taxes
      including  taxes  based on income)  for 12  consecutive  calendar  months
      within a period of 15 calendar months  immediately  preceding the date of
      such  issuance is equal to at least one and one-half  times the aggregate
      of all  interest  charges  on  indebtedness  of the  Corporation  and its
      subsidiaries  on a  consolidated  basis  (excluding  interest  charges on
      indebtedness  to be retired by the  application  of the proceeds from the
      issuance of such preferred  stock) and the annual  dividend  requirements
      on all  preferred  stock of the  Corporation  and its  subsidiaries  on a
      consolidated  basis  (including  dividend  requirements  on all preferred
      stock  ranking as to dividends or assets prior to or on a parity with the
      preferred  stock to be  issued)  which  will be  outstanding  immediately
      after  the  issuance  of  such  preferred  stock;  and  unless  (ii)  the
      aggregate par value,  or stated capital  represented  by the  outstanding
      shares  of the  junior  stock  of  the  Corporation,  including  premiums
      thereon  plus any  surplus  of the  Corporation  is equal to at least the
      aggregate  amount payable in connection  with an involuntary  liquidation
      of the  Corporation  with  respect to all shares of the Class A Preferred
      Stock and all  shares of stock,  if any,  ranking  prior  thereto or on a
      parity  therewith as to dividends  or assets,  which will be  outstanding
      immediately  after  the  issuance  of such  preferred  stock.  If for the
      purpose  of  meeting  the  requirements  of  clause  (c)(ii)  immediately
      preceding  it shall have been  necessary to take into  consideration  any
      earned surplus of the Corporation,  the Corporation  shall not thereafter
      pay any  dividends  on,  or make any  distributions  in  respect  of,  or
      purchase  or  otherwise  acquire,  junior  stock  which  would  result in
      reducing  the  junior  stock  equity  to an amount  less than the  amount
      payable on  involuntary  liquidation of the  Corporation  with respect to
      all shares of the Class A Preferred  Stock and all shares  ranking  prior



      to or on a parity with the Class A Preferred  Stock as to  dividends  and
      assets at the time  outstanding.  If,  during the period for which  gross
      income is to be  determined  for the purpose set forth in clause  (c)(ii)
      above, the amount required to be expended by the Corporation  pursuant to
      a  maintenance  fund or  similar  fund  established  under  its  mortgage
      indenture shall exceed the amount deducted in the  determination of gross
      income on account of  depreciation  and  maintenance,  such excess  shall
      also be deducted in determining gross income; or

(d)   Issue or assume  any  unsecured  notes,  debentures  or other  securities
      representing unsecured indebtedness for any purpose other than

              (i)    the refunding of unsecured indebtedness theretofore
          created or assumed by the Corporation and then outstanding;

              (ii)   the reacquisition, redemption or other retirement of any
          indebtedness, whether secured or unsecured, which reacquisition,
          redemption or other retirement  has been  authorized  by any state or
          federal  regulatory authority; or

              (iii)  the  reacquisition,  redemption  or other  retirement  of
          outstanding shares of one or more series of preferred stock of the
          Corporation;

          if  immediately  after such issue or assumption  the total  principal
          amount  of  all  unsecured  notes,  debentures  or  other  securities
          representing   unsecured   indebtedness  issued  or  assumed  by  the
          Corporation  (including  unsecured  indebtedness then to be issued or
          assumed)  would exceed  twenty per centum  (20%) of the  aggregate of
          (1) the  total  principal  amount  of all  bonds or other  securities
          representing   secured   indebtedness   issued  or   assumed  by  the
          Corporation  and then to be outstanding  and (2) the par value of, or
          stated capital  represented by, the shares of all classes of stock of
          the  Corporation  then to be  outstanding in the hands of the public,
          plus premium on such stock, plus capital surplus,  earned surplus and
          any  other  surplus  of the  Corporation  as then to be stated on the
          books of account of the Corporation.

X.    So long as any shares of the Class A Preferred  Stock of any series shall
      be outstanding,  the Corporation  shall not,  without the consent by vote
      or in writing of the  holders  of  two-thirds  of the number of shares of
      the  Class A  Preferred  Stock  of all  series  at the  time  outstanding
      considered  as a class without  regard to series,  authorize any class of
      stock  ranking  prior to the Class A Preferred  Stock with respect to the
      payment of dividends or the  distribution of assets upon the dissolution,
      liquidation  or  winding  up of the  Corporation,  whether  voluntary  or
      involuntary.

XI.   So long as any shares of the Class A Preferred  Stock of any series shall
      be outstanding,  the  Corporation  shall not change the express terms and
      provisions  of the  Class A  Preferred  Stock as to such  series so as to
      affect such series  adversely,  without the consent by vote or in writing
      of the  holders  of  two-thirds  of the  number  of  shares  of  Class  A
      Preferred Stock of all series so affected,  considered as a class without
      regard to series.


                     Rights of Class A Preferred Stock on
                    Liquidation, Dissolution or Winding Up
                    --------------------------------------

XII.  In the event of any  liquidation  or  dissolution  or  winding  up of the
      Corporation  the  holders of the Class A  Preferred  Stock of each series
      shall be entitled to receive,  in  preference  to the Common  Stock,  but
      pari passu with any additional class of cumulative  preferred stock which
      may  be  authorized  pursuant  to  the  provisions  of  Paragraph  10  of
      Section 2 of Article IV of these  Articles of  Incorporation,  out of the
      assets   of  the   Corporation   available   for   distribution   to  its
      stockholders,  before  any  distribution  of assets  shall be made to the
      holders  of  any  class  of  junior  stock,  (i)  if  such   liquidation,
      dissolution or winding up shall be involuntary,  the sum of fifty dollars
      ($50) per share  plus full  cumulative  dividends  thereon to the date of
      final  distribution  to the  holders of the Class A  Preferred  Stock and
      (ii) if such  liquidation,  dissolution or winding up shall be voluntary,
      the  amount  per  share  fixed by the  Board  of  Directors  pursuant  to
      Paragraph II of this Class A Part plus full cumulative  dividends thereon
      to the  date  of  final  distribution  to the  holders  of  the  Class  A
      Preferred  Stock.  If upon any  liquidation  or dissolution or winding up
      of  the  Corporation   the  net  assets  of  the  Corporation   shall  be
      insufficient  to pay the  holders  of all  outstanding  shares of Class A
      Preferred  Stock the full  amounts  to which they  respectively  shall be
      entitled,  the holders of shares of Class A Preferred Stock of all series
      shall  share  ratably  in any  distribution  of assets  according  to the
      respective  amounts  payable in  respect of the shares  held by them upon
      such  distribution if all amounts payable on or with respect to the Class
      A  Preferred  Stock of all series  were paid in full.  Neither the merger
      nor consolidation of the Corporation into or with any other  corporation,
      nor the merger or  consolidation  of any other  corporation  into or with
      the Corporation,  nor a sale, transfer or lease of all or any part of the
      assets  of  the  Corporation,  shall  be  deemed  to  be  a  liquidation,
      dissolution or winding up of the Corporation.

                              Certain Definitions
                              -------------------

      Systems  of  Accounts   prescribed  by  regulatory   commissions   having
      jurisdiction  over  the  Corporation  and its  subsidiaries.  The  amount
      deducted for maintenance and  depreciation of property of the Corporation

      Class A Part with  reference  to any  share of any  series of the Class A
      Preferred  Stock shall be deemed to mean  (whether or not in any dividend
      period or any part  thereof  in  respect of which such term is used there
      shall  have been net  profits or net  assets of the  Corporation  legally

      the period of time elapsed from the date of  cumulation of such series to
      the  date  as of  which  full  cumulative  dividends  are to be  computed
      (including  an amount  equal to a dividend  at such rate for the  elapsed
      portion of the current  dividend  period) less, in each case,  the amount

      Part,   shall  mean  the  aggregate  par  value  of,  or  stated  capital
      represented  by,  the  outstanding  shares  of the  junior  stock  of the
      Corporation   including   premiums   thereon  plus  any  surplus  of  the
      Corporation.

                The term  "junior  stock  equity  ratio"  shall mean the ratio,
      computed as of the end of the second  calendar  month  preceding the date
      of  the   authorization  by  the  Board  of  Directors  of  the  proposed

      the  shares  of  all  classes  of  stock  of  the   Corporation  and  its
      subsidiaries  outstanding in the hands of the pubic, plus premium on such
      stock  plus,  in the case of such  stock  of  subsidiaries,  any  surplus
      applicable thereto.

                     Redemption of Class A Preferred Stock
                     -------------------------------------

XIV.  The Class A Preferred Stock of all series,  or of any series thereof,  or
      any part of any series thereof, at any time outstanding,  may be redeemed
      by the Corporation,  at its election expressed by resolution of the Board
      of  Directors,  at any time or from time to time (which time,  when fixed
      in each case,  is herein after called the  "redemption  date"),  upon not
      less than  thirty (30) days  previous  notice to the holders of record of
      the  Class A  Preferred  Stock  to be  redeemed,  given  by  mail  and by
      publication  in a  newspaper  of general  circulation  in the  Borough of
      Manhattan,  City  and  State  of  New  York,  in  such  manner  as may be
      prescribed  by resolution or  resolutions  of the Board of Directors,  at
      the optional  redemption  price or prices fixed by the Board of Directors
      pursuant  to  Paragraph  II of this Class A Part then  applicable  to the
      Class A  Preferred  Stock to be  redeemed,  plus an amount  equal to full
      cumulative  dividends  thereon to the  redemption  date (the aggregate of
      which  amounts  is   hereinafter   in  this   Paragraph  XIV  called  the
      "redemption  price").  If less  than all the  outstanding  shares  of the
      Class A Preferred Stock of any series are to be redeemed,  the redemption
      may be  made  either  by  lot  or  pro  rata  in  such  manner  as may be
      prescribed  by  resolution  of the Board of  Directors.  The  Corporation
      may, if it so elects,  provide  moneys for the payment of the  redemption
      price by depositing  the amount thereof for the account of the holders of
      Class A Preferred  Stock entitled  thereto,  with a bank or trust company
      doing business in the Borough of Manhattan,  in the City of New York, and
      having   capital   and   surplus  of  at  least  Five   Million   Dollars
      ($5,000,000),  at any time prior to the redemption  date (the date of any
      such deposit being  hereinafter  called the "date of  deposit").  In such
      event,  the  notice  of  redemption  shall  include  a  statement  of the
      intention  of  the  Corporation  to  deposit  such  amount  prior  to the
      redemption  date and the name and  address  of the bank or trust  company
      with which the deposit  will be made.  On and after the  redemption  date
      (unless default shall be made by the Corporation in providing  moneys for
      the payment of the redemption  price),  or, if the Corporation shall make
      such  deposit on or before the date  specified  therefor  in the  notice,
      then on and  after  the date of  deposit,  all  dividends  on the Class A
      Preferred Stock thereby called for redemption  shall cease to accrue and,
      notwithstanding  that any  certificate  for  shares of Class A  Preferred
      Stock so  called  for  redemption  shall not have  been  surrendered  for
      cancellation,  the shares  represented  thereby shall no longer be deemed
      to be outstanding  and all rights of the holders  thereof as stockholders
      of the  Corporation  shall  cease  and  terminate,  except  the  right to
      receive  the  redemption  price as  hereinafter  provided  and except any
      conversion or exchange  rights not theretofore  expired.  Such conversion
      or exchange rights,  however, in any event shall cease and terminate upon
      the  redemption  date or upon any  earlier  date  fixed  by the  Board of



      Directors  pursuant  to  Paragraph  II of  this  Class  A  Part  for  the
      termination  of such rights.  The  Corporation  may pay in regular course
      any dividends  reflected in the redemption price either to the holders of
      record  on the  record  date  fixed  for  determination  of  stockholders
      entitled to receive such  dividends (in which event,  anything  herein to
      the contrary  notwithstanding,  the amount so deposited  need not include
      any  dividends  so paid  or to be  paid)  or as a part of the  redemption
      price upon  surrender of the  certificates  for the shares  redeemed.  On
      and  after the  redemption  date or, if the  Corporation  shall  elect to
      deposit the moneys for such  redemption as herein  provided,  then on and
      after  the  date  of  deposit,  the  holders  of  record  of the  Class A
      Preferred  Stock  to  be  redeemed  shall  be  entitled  to  receive  the
      redemption  price upon  actual  delivery  to the  Corporation  or, in the
      event of such a  deposit,  to the bank or trust  company  with which such
      deposit is made,  of  certificates  for the shares to be  redeemed  (such
      certificates,  if required,  to be properly stamped for transfer and duly
      endorsed in blank or accompanied by proper  instruments of assignment and
      transfer  thereof duly endorsed in blank).  Any moneys so deposited which
      shall remain  unclaimed by the holders of such Class A Preferred Stock at
      the end of six (6) years after the redemption  date shall be paid by such
      bank or trust company to the  Corporation;  provided,  however,  that all
      money so  deposited,  which  shall not be  required  for such  redemption
      because of the exercise of any right of conversion or exchange,  shall be
      returned to the  Corporation  forthwith.  Any interest  accrued on moneys
      so deposited shall be paid to the Corporation from time to time.

                      Purchase of Class A Preferred Stock
                      -----------------------------------

XV.   The  Corporation  may,  from time to time,  subject to the  provisions of
      Paragraph  II of this  Class A Part,  purchase  the  whole of the Class A
      Preferred  Stock  or any  series  thereof,  or  any  part  of any  series
      thereof, upon the best terms reasonably obtainable,  but in no event at a
      price  greater  than  the  then  current  redemption  of  the  shares  so
      purchased.
